Abstract
The invention relates to a method of controlling a hydrogenation of a starting material in a hydrogenation reactor, in which the amount of hydrogen reacted in the hydrogenation is firstly determined, the ratio of the amount of hydrogen reacted to the amount of starting material fed in is then derived, this ratio is compared with a prescribed value and, finally, at least one process parameter is altered if the ratio of the amount of hydrogen reacted to the amount of starting material fed in deviates by a prescribed amount from the prescribed value.
Claims19
A method of controlling a hydrogenation of a starting material in a hydrogenation reactor, which comprises the following steps:
- a) determining the amount of hydrogen reacted in the hydrogenation,
- b) determining the ratio of the amount of hydrogen reacted to the amount of starting material fed in,
- c) comparing the ratio derived in step b) with a prescribed value and
- d) altering at least one process parameter if the ratio derived in step b) deviates by a prescribed amount from the prescribed value.
